In some countries where there are avaliable jobs, we have people working on 1, 2, 3 jobs so for such a person he already have an alternative and can easily switch for a better offer no problem.
What is a problem is when you quite your job, without any alternative, i mean you enrolled yourself into the unemployed academy, also is important to develop some skills amd training, that way when youare out of job, you have something to fall back to.
Ops can you include a link to your quote as a form of reference.
do you know that it is hardly before you see someone quitting from his job without having an alternative , sometimes some people miss their opportunities because of misinformation from other people who try to deceive them and that is why they will quit their job without making sure that they have secured another one before leaving the present job they are, that is why I said it is very difficult before something like that happen because many people now have grown to the level that they think beyond what will happen tomorrow, and the another thing is that those people who work on contract there are people who likely to quit their job without having alternative because they believe that if they go out in search of work they will get a similar job
